To participate in the IPhO, students must be nominated by their national committees, which select teams of students based on their performance in national physics competitions or other selection processes. The competition consists of a written examination and an experimental and theoretical practical examination.
The written examination consists of five to six questions, which test the students’ understanding of fundamental concepts and their ability to solve problems using physics principles. The practical examination consists of experiments and activities that test the students’ skills in laboratory work and data analysis.
The IPhO is held in a different country each year and attracts hundreds of participants from around the world. The competition is held over a period of several days, and students are accompanied by their national coordinators and chaperones.
The winners of the IPhO are awarded gold, silver, and bronze medals, and all participants receive certificates of participation. The IPhO is a prestigious event that is highly respected in the scientific community, and many top universities and research institutions actively seek out and recruit students who have participated in the competition.
